New 3.10.18 Kernel for Xen4 needs testing
by Johnny Hughes 13 Nov '13

13 Nov '13

For anyone who is using our Xen4CentOS6 repo, we have created a new kernel from the new LTS 3.10.x kernel tree (to upgrade the current 3.4.x xen kernel) that we hope to roll into the production repo. Please look here and test the kernel, libvirt, and xen files there: http://dev.centos.org/centos/6/xen-c6-RC1/ That repo should be able to be used for testing or it should be able to update a current xen4centos6 repo as well ... the packages are signed by the testing key and I am currently using them, but YMMV, so be careful. Please also provide feedback (both positive and negative) so we can move these into production. NOTE: after installing a new kernel, please run "/usr/bin/grub-bootxen.sh" ... OR ... manually edit your "/boot/grub/grub.conf" file to boot the new kernel on your dom0 machine. Thanks, Johnny Hughes

Hi all, How can I avoid sharing interrupts in a kvm guest? I have installed a debian 7 guest in a centos 6.4 host with 5 virtio vnics and 2 virtio disks and irq11 is used by eth2, eth3, eth4 and irq10 eth0, eth1 ... Is it possible to avoid this situation?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

USB redirection under CentOS 6.4
by carlopmart 04 Oct '13

04 Oct '13

Hi all, Does usb redirection works?? I am trying to assign to a Win7 kvm guest an usb HP printer without luck ... My second attempt is to use usb redirection, but according to Redhat's docs, this option is only available for windows using RHEV ... Is this correct?? Exists another tool to assign a printer via usb to a kvm guest?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Re: [CentOS-virt] Upgrade of CentOS and libvirt: need help on configuring network - Solved

Solution was relatively easy and mainly a matter of understanding the "ifcfg-eth0 - like" files. What I did: 1 - yum install bridge-utils 2 - change /etc/sysconfig/network-scripts/ifcfg-eth0 to: DEVICE="eth0" BOOTPROTO=none ONBOOT="yes" TYPE="Ethernet" HWADDR=xx:xx:xx:xx:xx:xx BRIDGE="br0" USERCTL=no IPV6INIT=no NM_CONTROLLED="no" 3 - change change /etc/sysconfig/network-scripts/ifcfg-br0 to: DEVICE="br0" BOOTPROTO=none ONBOOT="yes" IPADDR=192.168.0.95 NETMASK=255.255.255.0 GATEWAY=192.168.0.1 DNS1="192.168.0.1" PEERDNS="yes" TYPE="Bridge" DELAY=0 STP=off USERCTL=no IPV6INIT=no NM_CONTROLLED=no 4 - /etc/init.d/network restart 5 - choose Host device eth0 (Bridge 'br0') in the VM-manager GUI for the virtual-machine's NIC 6 - restart the virtual machines That made it all work. So what I had wrong initially were settings in the ifcfg-xxx files. There are different settings that may work and I just tried some of the not-working combinations. Cheers, Koos.
